I’ve noticed a similar problem, but under slightly different circumstances, everything runs fine (Firefox, videos etc.) and typically the Xorg process is always less that 10%.
My problem occurs when a seconds user logs on, for example the screen saved comes on, my gf clicks “switch user”/“change user” or whatever its called, she logs in and the CPU usage of Xorg process shoots through the roof, especially when using Firefox. My setup is as below: OS: Ubuntu 9.10 (Karmic) CPU: AMD Athlon 64 3200+ (Venice/San Diago Core) Memory: 2GB PC3200 Corsair Video Card: ATI X1800 (R520) Driver: Open Source radeon (NOT radeonhd) I’ve tinkered with some of the Xorg.conf settings, and if I set the AccelMethod to the older XAA mode instead of EXA, the problem doesn’t exhibit itself. Unfortunately I cannot play videos using XAA mode. I’m guessing it’s a problem with the open source radeon driver and EXA Accel method (in my case at least). -- Firefox causes massive Xorg CPU usage https://bugs.launchpad.net/bugs/38131 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
